This pull request aims to fix the issue of excessive nesting brought up in the following comment: https://github.com/prettier/prettier/issues/737#issuecomment-392541493
This "fix" is very simple. It adds a new possible way to activate JSX mode for ternary operators. If the first non-conditional parent of the expression is a JSX expression container, then JSX mode gets activated.
This branch also contains a test case for said scenario.
* Now JSX-mode ternaries only break if they need to.
* Only the outermost ternary in a chain of JSX-mode ternaries will become a group.
* We don't wrap null in parens when breaking JSX-mode ternaries.
This commit also improves the test coverage and explanation in tests/jsx/conditional-expression.js.
* Arrow Function Expressions returning JSX will now add parens when the JSX breaks
* Conditional expressions within (or containing) JSX are formatted in a more natural way (for JSX), especiall when chained
* JSX in logical expressions (|| or &&) is always wrapped in parens
Fixes#2208
* Allow JSX lines to be recombined
* Add test case for `<br />` breaking expression
* Fix issue where JSX whitespace could be dropped
* Newlines were incorrectly being preserved when JSX contained text
I didn't intend for putting parenthesis there in the first place but it slept through. Since it was going to trigger a ton of changes I held up changing it, but I feel like we need to do it sooner than later otherwise we're not going to be able to do it. A lot of people writing functional components are going to be very happy about this change :)
This is very unfortunate that we have to change the generic function that prints code but we want the JSXElement node to handle its comments printing itself in order to write them inside of the parenthesis instead of outside.
Fixes#555
* Add exceptions for html escape usage in href and src attributes.
* Add new test cases.
* Remove useless spaces.
* Do not escape if the parser does not do so.
* Implement a different heuristic for keeping along with the parser.
* Update tests.
* Forgot passing options as param.
* Experimental alternative implementation.
* Remove other function.
* Push test after merge.
* Update getJsXRawValue in order to return the unprocessed raw value.
Latest Babylon version includes a fix that allow us to directly
inject the unprocessed raw value available in the `extra.rawValue`
property of the node. A last transformation is applied by replacing
double quotes to `"` entities.
* Drop unused htmlEscapeInsideDoubleQuote function.
* Move getJSXRawValue function logic to the its only call, drop it.
A simple check is performed to determine if the parser is babylon or
flow via `n.value.extra`. Thus, the corresponding raw value is
extracted. If we are converting a string from single quotes to
double quotes, we need to make sure that double quotes are converted
to ".
* Remove ambiguous comment.
* Add Babylon parser.
* Update test cases accordingly, revert regression introduced previously.
* Verify parsers against same snapshot
- Reworked run_spec, now accepts 3th optional array argument for
additional parsers to verify against
- Merged duplicate run_spec configs
- Removed duplicate snapshot data
* Formatted run_spec.js with prettier
* Fixed node4 incompatibility
* Revert "Remove mutation in `printBinaryishExpressions` (#1067)"
This reverts commit e7312ad7b2.
* Revert "Make it clear what parser was used in each snapshot (#1068)"
This reverts commit 4f7ae4815b.
* WIP immediate feedback
* typescript parser is drop-in replacement for flow parser
* Add new TypeScript Parser snapshots where drop-in replacement possible
* Snapshot updates after rebasing
* Remove unnecessary stripping of properties on TypeScript parser AST
* Remove annotated issues
* Move TS dependencies to dev for now
Conditionals are very common in JSX and it is unfortunate that they take up so much vertical space in the current prettier.
This pull request does a few tweaks:
- It hugs ConditionalExpression (ternary) and LogicalExpression (&&) inside of `{}` in a jsx child, not an attribute
- It doesn't output parenthesis if your parent is a LogicalExpression (&&)
Fixes#317
